Find LCM of 670,429,336,755,126 with Prime Factorization
| 2 | 670, 429, 336, 755, 126 |
| 3 | 335, 429, 168, 755, 63 |
| 5 | 335, 143, 56, 755, 21 |
| 7 | 67, 143, 56, 151, 21 |
| 67, 143, 8, 151, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 67 x 143 x 8 x 151 x 3 = 7291524240
Therefore, the lowest common multiple of 670,429,336,755,126 is 7291524240.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
670 x 429 x 336 x 755 x 126 = 9187320542400
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
670 : 1, 2, 5, 10, 67, 134, 335, 670
429 : 1, 3, 11, 13, 33, 39, 143, 429
336 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 42, 48, 56, 84, 112, 168, 336
755 : 1, 5, 151, 755
126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 670,429,336,755,126, is 1.
Now, the common factors can be found like this.
670:2x 5x 67
429:3x 11x 13
336:2x 2x 2x 2x 3x 7
755:5x 151
126:2x 3x 3x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 3x 5x 7 = 1260
Therefore, the value for common factors is 1260.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 9187320542400/(1x1260)
LCM = 9187320542400/1260
LCM = 7291524240
Thus, we can understand that the LCM of 670,429,336,755,126 is 7291524240.
